Abstract

Se proporciona un dispositivo de descontaminación por láser de recombinación y un método para la descontaminación radiactiva de un componente de planta de energía nuclear. El dispositivo de descontaminación por láser de recombinación comprende al menos dos módulos transmisores de láser, módulos de conformación de haz correspondientes a los módulos transmisores de láser, y un módulo de conformación de láser, el láser emitido por el módulo transmisor de láser ingresa a los módulos de conformación de haz correspondientes para conformar el haz y luego ingresa al módulo de conformación de láser para la conformación del láser; finalmente, se produce la salida a una superficie de una base a descontaminar del componente de planta de energía nuclear; el ancho de pulso del láser emitido por cada módulo transmisor de láser es diferente, y se determina encender un módulo transmisor de láser correspondiente en base a una condición de depósito sobre la superficie de la base a descontaminar. La presente solicitud propone una solución de descontaminación por láser de recombinación para la descontaminación de plantas de energía nuclear y selecciona un módulo transmisor de láser correspondiente de acuerdo con la situación real de la superficie a descontaminar.A recombination laser decontamination device and a method for radioactive decontamination of a nuclear power plant component are provided. The recombination laser decontamination device comprises at least two laser transmitter modules, beam shaping modules corresponding to the laser transmitter modules, and a laser shaping module, the laser emitted by the laser transmitter module enters the corresponding beam shaping modules to shape the beam and then enter the laser shaping module for laser shaping; finally, a base to be decontaminated of the nuclear power plant component is released onto a surface; the pulse width of the laser emitted by each laser transmitter module is different, and it is determined to turn on a corresponding laser transmitter module based on a deposition condition on the surface of the base to be decontaminated. The present application proposes a recombination laser decontamination solution for the decontamination of nuclear power plants and selects a corresponding laser transmitter module according to the actual situation of the surface to be decontaminated.
